NAME
xcb_get_atom_name - SYNOPSIS
#include <xcb/xproto.h> Request function xcb_get_atom_name_cookie_t xcb_get_atom_name(xcb_connection_t *conn, xcb_atom_t atom); Reply datastructure typedef struct xcb_get_atom_name_reply_t { uint8_t response_type; uint8_t pad0; uint16_t sequence; uint32_t length; uint16_t name_len; uint8_t pad1[22]; } xcb_get_atom_name_reply_t; Reply function xcb_get_atom_name_reply_t *xcb_get_atom_name_reply(xcb_connection_t *conn, xcb_get_atom_name_cookie_t cookie, xcb_generic_error_t **e); Reply accessors char *xcb_get_atom_name_name(const xcb_get_atom_name_request_t *reply); int xcb_get_atom_name_name_length(const xcb_get_atom_name_reply_t *reply); xcb_generic_iterator_t xcb_get_atom_name_name_end(const xcb_get_atom_name_reply_t *reply); REQUEST ARGUMENTS
conn The XCB connection to X11. atom TODO: NOT YET DOCUMENTED. REPLY FIELDS
response_type The type of this reply, in this case XCB_GET_ATOM_NAME. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other. sequence The sequence number of the last request processed by the X11 server. length The length of the reply, in words (a word is 4 bytes). name_len TODO: NOT YET DOCUMENTED. DESCRIPTION
RETURN VALUE
Returns an xcb_get_atom_name_cookie_t. Errors have to be handled when calling the reply function xcb_get_atom_name_reply. If you want to handle errors in the event loop instead, use xcb_get_atom_name_unchecked. See xcb-requests(3) for details. ERRORS
This request does never generate any errors. SEE ALSO

NAME
xcb_intern_atom - Get atom identifier by name SYNOPSIS
#include <xcb/xproto.h> Request function xcb_intern_atom_cookie_t xcb_intern_atom(xcb_connection_t *conn, uint8_t only_if_exists, uint16_t name_len, const char *name); Reply datastructure typedef struct xcb_intern_atom_reply_t { uint8_t response_type; uint8_t pad0; uint16_t sequence; uint32_t length; xcb_atom_t atom; } xcb_intern_atom_reply_t; Reply function xcb_intern_atom_reply_t *xcb_intern_atom_reply(xcb_connection_t *conn, xcb_intern_atom_cookie_t cookie, xcb_generic_error_t **e); REQUEST ARGUMENTS
conn The XCB connection to X11. only_if_exists Return a valid atom id only if the atom already exists. name_len The length of the following name. name The name of the atom. REPLY FIELDS
response_type The type of this reply, in this case XCB_INTERN_ATOM. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other. sequence The sequence number of the last request processed by the X11 server. length The length of the reply, in words (a word is 4 bytes). atom TODO: NOT YET DOCUMENTED. DESCRIPTION
Retrieves the identifier (xcb_atom_t TODO) for the atom with the specified name. Atoms are used in protocols like EWMH, for example to store window titles (_NET_WM_NAME atom) as property of a window. If only_if_exists is 0, the atom will be created if it does not already exist. If only_if_exists is 1, XCB_ATOM_NONE will be returned if the atom does not yet exist. RETURN VALUE
Returns an xcb_intern_atom_cookie_t. Errors have to be handled when calling the reply function xcb_intern_atom_reply. If you want to handle errors in the event loop instead, use xcb_intern_atom_unchecked. See xcb-requests(3) for details. ERRORS
xcb_alloc_error_t TODO: reasons? xcb_value_error_t A value other than 0 or 1 was specified for only_if_exists. EXAMPLE
/* * Resolves the _NET_WM_NAME atom. * */ void my_example(xcb_connection *c) { xcb_intern_atom_cookie_t cookie; xcb_intern_atom_reply_t *reply; cookie = xcb_intern_atom(c, 0, strlen("_NET_WM_NAME"), "_NET_WM_NAME"); /* ... do other work here if possible ... */ if ((reply = xcb_intern_atom_reply(c, cookie, NULL))) { printf("The _NET_WM_NAME atom has ID %u0, reply->atom); free(reply); } } SEE ALSO
